Re: Mountain Coal Company, LLC, West Elk Mine; Permit No. C-80-007; Minor Revision No. MR-354,
Geotechnical and Sod Sample Boreholes for East Refuse Pile Expansion Area
Dear Mr. Hernandez:
Mountain Coal Company, LLC (MCC) provides the following responses to address the adequacy comments in
your May 20, 2009 e-mail correspondence.. The responses follow the questions and are preceded by an
asterisk.
1. I believe the pages of the West Elk Mine permit that (at this stage) are to be revised are 2.05-15, 2.05-16,
2.05-17, 2.05-28, and 2.05-29. Please let us know if our list agrees with MCC's list. If the revised permit
pages requested in the first part of this e-mail changes this list, let us know that as well.
* The permit pages that were changed included pages 2.05-25 and 2.05-26 for the field-designed light-use
road, and pages 2.05-28 and 2.05-28a for the new monitoring, sampling, drilling and other temporary
facilities or operations discussions.
2. MCC should propose a method to incorporate the May 5, 2009 Barr Engineering Memorandum (and its
accompanying two Figures) from Paul Swenson, Jed Greenwood, and Brad Dunn to Chris Nyikos and
yourself into the West Elk Permit. This could be done by submitting the memo as a new Exhibit to the
permit, or a new Appendix, or some other such new addendum. Please let us know how this memo and its
two figures will be incorporated into the West Elk Permit, and provide any necessary cover/title page that
might precede the memo in the Permit.
* In response to a similar question in the Mid-term #6 permit review, MCC has agreed to add similar
approved minor or technical revision documents to Volume 11A-C of the permit document. The TR-117
(MT-6 Responses) Table of Contents pages have been corrected for submittal in a separate document (re:
TR-117) to refer to the past thermal event and past and future MDW, geotechnical borehole and
miscellaneous approved (MR/TR) documents as Exhibit 80 in Volumes 11A-C of the permit. A reference
to Exhibit 80 has been added to both discussions provided in the attached revised permit pages.
3. I believe the proposed acreage for new disturbance is 0.6 acres, all on private land, with no increase in
permit area. Please let us know if these statements are correct.
* The proposed estimated disturbance is 0.6 acres
